jweber / slackbotnet Goto Github PK

Hello! I use your library in my project https://github.com/KonH/DotNetCoreBuildServer and ran into a problem, which I can resolve on my side (as I know it). I use your library there - https://github.com/KonH/DotNetCoreBuildServer/blob/master/Server/Integrations/SlackService.cs.

Steps to reproduce:

1. Initialize bot normally
2. Disable internet connection (simulate network problems)
3. Try to send any message
4. Observe results

Actual result:

Unhandled Exception: System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.Http.WinHttpException: Не удается разрешить имя или адрес сервера

When "Не удается разрешить имя или адрес сервера" is something like "Cannot resolve host name".

Excepted result:
Exceptions like this can be handled by library or provide some methods to handle it to library user code

Is something wrong with my integration? Or it can be fixed/improved inside library?
Waiting for your feedback, maybe I can help with it.

If I mention the app directly, it works. However, when I use a slash command and point it to my endpoint, it doesn't respond.

Hello!
We faced with a problem, which can be reproduced in our environment when bot is running for a long time. Sometimes it denied to respond and as I see, it's related to websocket connection, which hangs in Aborted state.
I have made dirty workaround with reflection, because don't want to modify sources (now it used in several apps), I hope this commit helps to understand the problem - KonH/DotNetCoreBuildServer@7b16dfe.

Hi! We faced to another issue with unhandled exception in ping-pong progress, and as I see we can't handle it on our side.

Steps to reproduce:

• Start bot
• Disable network connection
• Wait several seconds

Details:
Exception is at SlackRtmDriver.cs:75:
